Claims (11)

1. A method of managing, regulating and/or controlling energy consumed by a group of energy consuming devices, where the energy consuming devices may increase or decrease a physical parameter, the method comprising the steps of receiving a message from a controller either to decrease or to increase the energy consumption, and where the decrease or increase in the energy consumption is achieved by changing the physical parameter.
2. A method of managing, regulating and/or controlling energy consumed by a group of energy consuming devices according to claim 1, wherein each energy consuming device being in the process of increasing its physical parameter is instructed to stop increasing its physical parameter when the message is to decrease the energy consumption, and each energy consuming device being in the process of decreasing its physical parameter is instructed to start increasing its physical parameter when the message is to increase the energy consumption.
3. Method according to claim 2, wherein the energy consuming devices set to operate within a range of the physical parameter defined by a minimum physical parameter and a maximum physical parameter.
4. Method according to claim 3, wherein each energy consuming device overrules the message and changes stage when reaching the minimum or maximum physical parameter, so that the energy consuming device changes to decrease the physical parameter when it reaches the maximum physical parameter and changes to increase the physical parameter when it reaches the minimum physical parameter.
5. Method according to claim 4, wherein the physical parameter is a temperature.
6. Method according to claim 5, wherein the energy consuming devices are either refrigeration or freezing devices.
7. Method according to any of the preceding claims, wherein the message is related to ripples on the power grid in such a manner that the message is to decrease energy consumption when the total energy delivered by the power grid increases above an expected delivered energy span, and to increase energy consumption when the total energy delivered by the power grid decreases below an expected delivered energy span.
8. Method according to claim 7, wherein the ripples are any fluctuations in the energy delivered by the power grid from the expected delivered energy span having time spans less that 30 minutes, or more preferable less than 15 minutes, or more preferable less than 10 minutes.
9. Method according to claim 7 or 8, wherein the expected delivered energy span is dynamic in time, meaning that it varies over at least one day and night and optionally also over a month and/or a year.
10. Method according to claim 9, wherein the expected delivered energy span being dynamic in time depends on one of or a combination of empiric data of the energy delivered by the power grid seen over the day, month and/or year, an adaptive model predicting the energy delivered by the power grid, and/or the external weather conditions such as temperature, sunshine, cloudiness, barometric state and humidity.
11. The system operating by the method of any of the preceding claims.
